My personal background is actually very unusual for the kind of career I chose. I didn’t meet anyone who had ever done physics in my life. I grew up in the Himalayan forests. My father was a forest conservator, which meant that if I wasn’t in school I was in the forests with him. That has been very largely responsible for my ecological inclinations.

Something is very, very wrong when people don’t have access to drinking water, and Coke creates its market out of that scarcity.

Uniformity is not nature's way; diversity is nature's way.

When I find too many puzzles about the way explanations are given about why there is inequality - why people who work the hardest in the world end up being the poorest - I can't just sit back and not try to understand why the gaps between people are increasing, or why there are so many homeless and hungry people in the world.

You cannot insert a gene you took from a bacteria into a seed and call it LIFE. You have not created life, instead you have only polluted it.

My links with [Mahatma] Gandhi now are very political links because I do not believe there is any other politics available to us in the late twentieth century, a period of a totalitarianism linked with the market. There is really no other way you can do politics and create freedom for people without the kinds of instruments he revived. Civil disobedience is a way to create permanent democracy, perennial democracy, a direct democracy.

Genetic engineering has never been about saving the world, it's about controlling the world.
